Question

The ratio of the dimension of Planck's constant and that of the moment of inertia is the dimension of :

• A. Velocity
• B. Angular momentum
• C. Time
• D. Frequency

Answer 1

The correct option is D Frequency

$\frac{h}{I}\equiv \frac{J.sec}{Kg.m^2}\equiv \frac{M{L}^2{T}^{-1}}{M{L}^2}=\frac{1}{T}\equiv frequency$

Hence, option D is correct.
